HENRY c. MILLER, OFWATERFORD, NEW YORK.

, LOADER FOR BUTTONHOLE-MALCHINES.

Specification of Letters Patent. Patented Apr. 15, 1919.

Application filed January 31, 1918. Serial No.'214,654.

To all whom it mayconccm Be' it known that 1,.HENRY citizen of the United States of America, re-

siding at Waterford, in the county of Saratoga and State of New York, have invented certain new and useful Improvements. in Loaders for Buttonhole-Machines, of which This invention relates to improvements in machines for locating buttonholes in: collars, better known in the art as loaders for buttonhole machines. a m r V Heretofore loaders. for. this purpose have been mounted to slide-horizontally toward the buttonhole machines, such for instance as disclosed in myprior Patents Nos. 793,066, June 20, 1905, and 793,010, June 20, 1905..

In mypresent construction the loader ismounted to rock on a pivot and moves in an arcuate path toward and from the button: hole machines, the parts being so arranged that the edge of the loader in its delivery movement snugly engages-the base of each buttonhole machine, which insures of collar tabs being placed snugly under the work clamp. I

Therefore, one oftheobjects ofmy present invention is to provide in a' pivoted loader, means whichwill enable the operator to quickly gage and insure-of a collar being held in gaged positionand introducedunder the work clamp of. the buttonhole machine.

.A further object of theinvention is to provide a loader with meansv for gaging a collar of any size and angle 'and insure of the'collar tabs beingrigidly and smoothly held in position while being introduced under the work clamps.

A still further object :of theinvention is to provide safety means which will prevent the operator forcing the loader with the rangement of partswhich will beherein gage collar thereon against the work clamps,

if the latter havenotbeen previouslylifted by theoperator.

The inventlon alsocomprehends improvements in the details of construction and arafter described and particularlyv pointed out in theclaims-h V In thedrawingsze-f H i V ,Figure l is a perspective view of the loader applied,'the buttonhole machines being but conventionally illustrated.

191,57 3; Whileit is not absolutely essential that the buttonhole machine referred to be employed in-connection with the present invention, yet there are connectionsto be described which are particularly adapted to a machine such as shown. 2 indicates a table, supported on a frame 3. Mounted on the top of the table 2,,in spaced relation, aretne buttonhole machines 1i1, each including a base 5, a work clamp 7, a needle bar 8, and stop mechanism 9. i

A bracket 12,. extends from the front of the table, and on a pin 13 at the outer end of this bracket is pivoted aframe 14, of approximately 8 shape in side view. A casting 15 is pivotallymounted on a pin 16, supported on the upper end of the frame 14, and this casting is secured to aplatform 17, and from the rear of said casting projects a rod 18.

On the upper edges of the platform are two fixed bars 19-19, and mounted in same near the forward ends is a shaft 20. Adjustable in the shaft. 20, and projecting rearwardly therefrom outside the side bars, are

22. These fingers normally fit in slots 23,

formed in the rear edgeof the zplatform,.i

and theyare formed of thin resilient wire to hold the collar tab flat, and to gently engage said tabs when a collariisgaged.

On'the inside of the rear end of each bar19, is a block 24, and adjustablyinount'ed therein by set screws'25, are-seam gages 26.

Each seam gage comprises a stout wire, bent upwardly at 28, and downwardly andrfor= wardly at 29, and thence downwardly and rearwardly at30. Thepurpose of so bend ing the gages is to form arches to allow ample room for the operators hands when gaging a collar on the platform, as will appear later on. 3 V Extending upwardly from theshaft20,is

. a breaker'rod 32, which is bent downwardly A and'rearwardly toward the rear ofthe plat-& form, the lower end resting on or close to thesurface-of the platform, and between the. two seamgages. A spring 33 is'attached'; to the vertical portion of the breaker bar,

and its rear end is attached to a studfextending upwardly from'the rod 18.

adjustable tab gages l7 17 Each tab gageis-cut at anangle on its rear edge, and

is also provided with a slight flange 17", the

inner'rear pointed end of each gage fitting in the tab crotch of a collar'when gaging the latter. Each 'gage is provided with a slot 17 through which-a set screw 17 passes to adjustably holdthe gage in set' position.

A standard 34 extends from the rear of the table, and it is provided with an opening-35," through which the rod 18 passes. The opening 35,is somewhat larger than the diameter of'the rodto permit free movement of the latter when {the loader is moved toward and from the buttonhole machines.

On, the rear end of the rod 18, is a buffer 37. Located some distance forward of the buffer 37 is a collar 38, and onthe rear face thereof is a bufi'er39; The buffer 39 abuts against the front ofithe standard 34, when the loader is forced rearwardly, while the buffer 37 abuts against the rear face of the standard when the loader is returned to normal position, the buffers of course being purpose of reducing shocks.- v V i A spring 40, is connected at its forward end to the frame 14,}and at'its rear end it is attached to the standard 34, the tension of the spring being to move the loader toward the buttonhole machines. V Y 7 A bracket 41 is bolted to the base of the standard 34, and it is, provided with two pivot pins 42, on which are pivoted two arms 43, each having a'semi-circular head 44, at its upper end, the inner edge of each Located on the top of the platform are two for the are brought together, they mbrace-the rod adjacent the front abutting surface of the opened againstthetension-of thespring. 46, and the loader returned to 'normalposition against :the tension off the spring 40,-by,:

manual; means, which will be described. later Extending. forwardly from the buttonhole machines are guides 45 the forward ends. of which incline downwardly. When the loader-is pushed rearwardly to deliver a gaged collar to the buttonhole machines, the rear 'edgeengages guides to guidethe plat form in its travel toward the work-"clamps.-

On the rear inner portionof each base of the buttonhole machines is a bracket46, and

ineach bracket is adjustably mounted a for wardly extended finger47, the free ends of the fingers beingbent upwardly; As show-11,

.hea 1 .having, a notch 45, and when said'h'eads or v 3 on each finger is a gage or stop 47 against which the rear edge of thecollar abuts when in position to be clamped; "These fingers are; dlsposed beyond the path of travel of the.

breaker'rod, and serve to prevent the central folded'or slack portion of the gaged collar! falling over on the workclamps, after the loader has delivered the collar to the buttonholemachines; *1 1 Mounted in the lowerpart of the frame is anarm 51, pivotally connected by a link 52, w1th a foot lever 53, pivoted*on a bracket 7 3, is a shaft 50, and 'extendingtherefrom 54, attached to the front edgeof the table 2.

A lever 54 isjfixed tothe shaft 50, and to the rear end thereof is secured a chain 54" attached to a. spring 55, and fastened to the other endof the-"sprlng are the lower ends of two diverging chains5'656; r Thechai'ns 56 are attached to: the upper ends'of' arms 57, mountedon shafts 58, which when turned in one direction rocks the'sh'aft 58,'and lifts the work clamps. Chains 61, connect the arms 43', with the lower ends of the levers 57, so

that at the'time the'work clamps 7- 7 are raised, the arms 43, will be rocked apart to remove the heads 44, from the path of the buifer 39, to permit the inner end of th'e loader to pass under the work clamps. 'Secured'to the forward end of the lever 54 1s a'chain 59*, which is trailed over a pulley 60, on the standard 34, and is fastenedat its 7 outer end to the collar 36 This-connection is for the purpose of ejectlng the loader'from under the lowered work clamps, just prior to the starting of thebuttonholemachines. To the lower ends of the levers 57, are attached chams 59, the inner ends of the latter being attached to the forward end of the lever 54,

the purpose of this connection being to reversely rock the shafts. 58, to start the buttonhole machines, and operate the trimmers, etc.

Let it be assumed that the parts are'inthe position shown in'Fig- 1, that is, the loader is in its normal position ready toreceive a collar, and the work clamps on the buttonhole machines are down. The operator de-' presses a treadle 70, which is connected by a chain with a lever 71, fast on the shaft'20,

which rocks said shaft and elevates the.

smoothing fingers 22, and the breaker bar 32, to the position shown in dotted: lines in Fig. 4. The operator nowgraspswithtwo hands, the opposite endsofa collar, and lays it over the breaker bar, holding the tab ends on theplatforrn and at thesame time pushes. the collar rearwardly until 'thetab' crotches a snugly engage the tab gages 17, as shown in dotted lines in Fig. 3. While gaging the tabs with the tab gages, the seam Z), of the collar is gaged by the ends of the seam gages 26, which of course, like the tab' gages, have been'set to locate the collar in the proper position to form the buttonholes in the tabs when the'collar ismoved underthe work.

clamps.

After the collar has been properly gaged, pressure on the treadle' is removed, and

the spring 33, lowers thesmoothing fingers and the breaker bar, the fingers bearing gently on the inner ends of the tabs to temporarily hold them down, while the breaker bar assumes its normal position on the plat- 7 form. By this means the collar is practi cally held clamped'to'the platform in position against the seam and tab gages, and is now ready to be delivered to the bottonhole machines. a

-When gaging the collar'no attempt. is made to stretch it; on the contrary the ends are drawn together by the operator," and the breaker bar, consequently a central loop or fold a, is formed in the' center of the collar,,between the two seam gages.

The operator. now rocks the foot lever 53, rearwardly from its neutral position shown in full lines at A in Fig. 2 to the dotted line position B, which, rough the lever 54 and the chains 56, rocks the shafts 58, and through connections not specifically described, elevates the work clamps 77, and simultaneously through the chains 61, spreads the arms 43, and opens the heads 44. At about the same time the loader is pushed rearwardly on the pivot 13, the rear edge of the platform engages and rides up on the guides 45. Immediatelythe spring 40 overcomes the wei ht of the loader, due to the upper end of t e frame 14 overhanging the'front of the pivot 13, the spring acts to carryzthe :loaderunder'the work clamps of the buttonhole machines',-.which, as revieously stated, are now elevated. The ufl'er 39, abuts againstthe standard 34, and limits the movement of the loader, the buffer -hav-.

ing been previously adjusted so that the tabs of the collar will lie in proper position underv the work clamps to receive the but.-

tonholes. The operator now rocksthe foot,

lever towardflthe -frontlof the-machine to its neutraliposition and the work clamps are lowered on the collar tabs, the light'resilient fingers being slightly pressedinto the fabric f by this action, but not enough to distortvthe tab, the slots 23 assisting in this function.

This movement also slackens thechainsfil,

and the spring 46 returns thearms 43 to permit the-heads to assume normalposition when the loader'is; withdrawn.

Further movement of the foot lever 53, toward the front of the machine past its neutral position, as shown in dotted lines at.

G, which, will cause the front end-ofQthe lever 54 to pull on thefchain =59 ,-l and promptly withdraw. the loader from under the work. clamps: 7, whereuponthe operator quickly restores the loader to its normal po'-. sition. The loader having been withdrawn from. the clamps, further, continuedmovement of the foot lever 53, causes the-front end of the lever 54 to pull on the chains 59 which rocks the shafts 58 in theopposite' and through mechanismnot f V specifically shown, the buttonhole-mechanismmis started, and-when the buttonholes; are rfinished, the :usual automatic j means stopsthe operation. When the loader is direction,

withdrawn against the tension of the spring 40, through the .mechanism-.described, im-

mediately the platform and associated'pa-rts pass over the vertical center of'the pivot the weight will overbalance the springand the loader moves from the rails-and settles to normal. position, the-buffer 37 :abuts againstthe stand-ard 34, and absorbs the shock, and. at the same time limits the: return movementof the parts. Whilethis movementis taking place, the operator hasanother collar lnhand ready to gage it forthenext operation. U

When the loader is pushed in to locate the tabs under the workclamps, the fingers 47 act to prevent the loop or fold in the slack portion of the collar falling on either of the clamps, while the rear edge of the collar engages the gages-47".

If, when the operator pushed the loader in, he neglected toraisethe work clamps, the

heads 44, on thearms 43,acts as a lockout and be interposed in the path of ,thebuffer 39. a The heads 44, form an abutment for the buffer 39, and the loader is lo'cked against further movement, hence the rear edge of i the platformis prevented from contacting wlth the front edges of the clamps, and

'This actioncauses the-rear edge of -the:plat-; form to bear snugly-on the rails, :which insures of-the collar being fitted closelyunder damage tb parts and dislocation of the gagedicollar is avoided, When this occurs, it serves as a warning to the operator that something is-wrong, astheparts are ar- "ranged to preclude accidents which'follow fromnegligenoe of this character.

Bythe construction described,'th'e mechanism is, protected against damage, and the collar is accurately gagedand-is positively held-in gaged position to properly locate the buttonholes. Furthermore, the construction is such that-fewer parts-are employed and therefore economy in up-keep is greatly-re-- ducedf Y 7 7 other; V

' Of course, the gages are set to accommovWhile the collar is gaged and introduced to the buttonhole -machines -manually, the

operation of forming the buttonholes is all automatically performed, and as previously stated, one operation is dependent on an:
